Dryer vent cleaning is not a fixed-price product, and anyone who gives you a firm number before asking a single question about your run is either guessing or planning to revise it on your driveway. Here is what genuinely moves the price, and what should not.
Why Nobody Can Quote It Properly Without Asking
Two houses on the same street can have dryer runs that differ by a factor of four in length and twice over in difficulty. One has the laundry in the garage, eight feet of straight metal duct, and a wall termination at waist height. The other has it upstairs, thirty feet of duct crossing an attic, five turns, and a cap on a tile roof. Those are not the same job, and pricing them the same would mean overcharging the first to subsidise the second.
So the questions a legitimate company asks on the phone — where is your laundry room, which floor, do you know where it vents out — are not a sales script. They are how the quote gets anchored to reality.
Five Things That Legitimately Move the Price
1. Length of the run
More duct is more work, straightforwardly. It also means more brush sections, more passes, and more time on site.
2. Number of turns
Turns matter more than length does. Each one is a place where the brush has to negotiate a bend and where lint has concentrated. A thirty-foot straight run is easier than a fifteen-foot run with four elbows.
3. Where it terminates, and whether we can get there
A wall hood at ground-floor height is simple. A roof cap adds access time, and on tile or a steep pitch it may not be safe to work at all — in which case we clean from the laundry side and tell you what we could not inspect, rather than charging for roof work we did not do.
4. How the appliance is installed
A freestanding dryer you can walk behind is minutes of access. A stacked unit bracketed into a closet, with the connection pinned behind it, takes longer and more care. Pedestal units, built-in surrounds and tight laundry closets all add time.
5. What we find once we are in there
This is the honest variable. If the run is dirty, cleaning handles it at the quoted price. If it turns out to be packed solid, that is blockage removal. If it is crushed, separated or made of foil, cleaning will not restore the airflow and you are looking at repair or replacement. We show you the problem in photographs and quote it separately so you can say no.
What Should Not Move the Price
- A number of vents. You have one dryer vent. A quote that multiplies a low per-vent price by the number of registers in your house is pricing something you did not ask for.
- Scare framing. A price that goes up in proportion to how alarming the description of your duct becomes is not a price, it is a tactic.
- Sanitising, deodorising or mould treatment add-ons. Not services we offer, and not things a dryer exhaust duct generally needs.
- A discount that expires while the technician is standing there. A real price is the same tomorrow.
Red Flags in a Quote
The pattern to watch for is a headline price low enough that nobody could do the work for it, followed by an on-site revision once the appliance is already pulled out and you are committed. Three specific warnings:
- A firm price quoted with no questions asked about your run.
- An unwillingness to give a range over the phone, paired with pressure to book a visit anyway.
- No mention of measuring anything. If the result is going to be described rather than measured, there is no way to tell whether it worked.
What We Do Instead
We ask about your laundry setup on the phone and give you a realistic range before anyone is dispatched. On site we trace the run and take a baseline airflow reading, and if what we find changes the job we tell you then, with photographs, before doing the extra work. When we are finished we measure again, so the result is two numbers rather than an assurance.
The useful question to ask any vent company is not what it costs. It is what they will show you afterwards to prove it worked.
If you want to know where your run stands before spending anything, the airflow test is free and takes under half an hour. Sometimes the answer is that nothing needs doing yet.
